python - Error with scrapy item object -

-

I'm having trouble with scrapbook items object The current problem is that when I scrap some fields, I Let me save them like this: 

  items ['tag'] = response Xpath ("// div [contains (@class, 'video-info-line show')]" "// [[(Half, '/ video / search search']] / text () () () () () () () () ()

There are more than one tag that scraps from each and the items are saved in ['tag'] I then on my SQL server Tags are uploaded and to get a mySQL syntax error. The problem is very obvious because it is trying to include something like this: 'tag1', youtag2, ittag 3, u I have tried because I have tried it ("", "") "" but it is not working.

You need to set the output processor for that specific field: < Import scrapper from scrapy.contrib.loader.processor Join class MyItem (scrapy.Item): My_field = scrapy.Field (output_processor = join (separator = ',')) < / Pre>

I'm trying to display a static page with Go. Go: Package main import "net / http" function main () {fs: = http.FileServer (http.Dir ("static / house")) Http: .handle ("/", fs) http.ListenAndServe (": 4747", zero)} directory: project / stable home Html edit.html project.go When I run it, the web page displays links to edit.html and home.html instead of displaying a static page from home.html is. What am I doing wrong. Is this the best way to serve files?
